  Elastic shoeUSPTO Application #: 20070033830Title: Elastic shoe Abstract: The present invention disclosed one of a pair of elastic shoes including a shoe body having a heel portion, and an elastic mechanism mounted on the heel portion of the shoe body. The elastic mechanism includes a plurality of air cells, and a plurality of plastic sleeves. The relatively higher elastic plastic sleeves are mounted around the air cells to produce a restoring force instantaneously when being subjected to the pressure, so that the elastic mechanism has an excellent resilience. Thus, the elastic shoe has excellent elasticity and shock-absorbing effect to provide a comfortable sensation to a user.

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to one of a pair of elastic shoes, and more particularly to an elastic shoe having excellent shock-absorbing effect to provide a comfortable sensation to a user. [0003] 2. Description of the Related Art [0004] A conventional elastic shoe in accordance with the prior art shown in FIGS. 9 and 10 comprises a shoe body 30 having a heel portion 31, and an elastic mechanism 40 mounted on the heel portion 31 of the shoe body 30 to provide an elastic shock-absorbing effect to the shoe body 30. The elastic mechanism 40 includes a plurality of elastic posts 41 each having an inside formed with a through hole 411. However, the elastic posts 41 cannot produce a restoring force instantaneously when being subjected to a pressure, so that the shock-absorbing effect of the elastic mechanism is limited greatly, thereby easily causing an uncomfortable sensation to a user. [0005] The closest prior art reference of which the applicant is aware was disclosed in the Taiwanese Patent Publication No. 521588. SUMMARY OF THE INVENTION [0006] In accordance with the present invention, there is provided an elastic shoe, comprising a shoe body having a heel portion, and an elastic mechanism mounted on the heel portion of the shoe body to provide an elastic shock-absorbing effect to the shoe body. The elastic mechanism includes a plurality of air cells, and a plurality of plastic sleeves each mounted around a periphery of a respective one of the air cells. [0007] The primary objective of the present invention is to provide an elastic shoe having excellent elasticity and shock-absorbing effect to provide a comfortable sensation to a user. [0008] Another objective of the present invention is to provide an elastic shoe, wherein the relatively higher elastic plastic sleeves are mounted around the air cells to produce a restoring force instantaneously when being subjected to the pressure, so that the elastic mechanism has an excellent resilience. [0009] A further objective of the present invention is to provide an elastic shoe, wherein the plastic sleeves having a relatively higher elasticity are mounted around the air cells to produce a restoring force instantaneously when being subjected to the pressure to prevent the elastic mechanism from losing its elastic force under the pressure, thereby enhancing the lifetime of the elastic mechanism. [0010] A further objective of the present invention is to provide an elastic shoe, wherein when the applied pressure disappears, the elastic mechanism can restore instantaneously by its excellent resilience so as to provide an enhanced shock-absorbing effect to the shoe body. [0011] A further objective of the present invention is to provide an elastic shoe, wherein when the air cells are subjected to a pressure, the air cells are connected with each other so that the applied pressure is distributed by the air cells smoothly and evenly, thereby enhancing the shock-absorbing effect of the elastic mechanism. [0012] A further objective of the present invention is to provide an elastic shoe, wherein the air cells and the plastic sleeves of the elastic mechanism are made by a plastic injection molding process, so that the elastic mechanism has a lighter weight, thereby decreasing the weight of the shoe body. [0013] Further benefits and advantages of the present invention will become apparent after a careful reading of the detailed description with appropriate reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS [0014] FIG. 1 is a perspective view of an elastic shoe in accordance with the preferred embodiment of the present invention.
